State of Pennsylvania, have invented certain mails, the envelop being easily and quickly opened to obtain the contents thereof.

ln the. accompanying draedngs, 1 designates the iront'pcrtion of the envelop the rear portion thereof, these portions being folded together upon the 5o line. The rear portion of the envc is provided with longitudinally arranged p rtoratione :lproviding a longitudinal searing dap The 'front portion of the envelop 'l is also pro-l vided with a similar ap 6, these ilaps being provided with adhesive material 7, whereby the confronting laces of said flaps can be secured together. I

'ilielrear portion of the envelop is pro)- vided with end flaps 8 and 9. 1i of these iiaps has the marginal portion oi" its inner face provided with adhesive' material il., and after the iiap 9 has been folded upon one side of the rear portion 2 of the envelop, the

The rear portion 2 now in condi-r tion to be folded upon the iront portion of the envelop, and after the liaps 8 and have been moistened, they are adhesiveiy secured to theinner side ci the iront portion 1 of the envelope; the space-between the rear portion 2 and the liaps 8 and 9 being sufficient to accommodate a letter.

The front portion of the envelop 1 is provided with end naps 12 and 13, each having,r the marginal portion of its inner face provided with adhesive material 14, whereby.

when these flaps are folded upon the dotted lines i5 they can be adhesively secured to the outer side of the rear portion 2 of the e11- velop, as clearl shown in Fig. 2 of the drawings. overlaps the flap 13, similar to the flap 8 overlapping the tlap 9. After the matter has been placed in the envelop, the longitudinal sealing edges 5 and 6 are secured together, and the envelop is securely closed.

To open the envelop it is only necessary to tear the longitudinal sealing flaps 5 and 6 oil' ofthe envelop, at which time easy access can be had to the interior thereof. The perforations i facilitate the removing of the longitudinal sealing liaps.
